T 0 all whom it may concern:

Be. it known that I, Riouano li. Unai-1N- noRF, a citizen ot' thelflnited States, and resident of the city of New "forli, ltichnioudHill, borough ot Queens, in the county ot Queens and citate ot' NewYork, have invented a new and ln'rproved Combined Liquid Separator andIndicator for Gao-Conduite, of which the following is a full, Clear, andexact description.

This invention relates to certain improvements in nie-ans forseparatingl liquids from gases and indicating 'when the liquid hascollected to euch an extent to prevent the free passage of the gas.

rl'he invention ie particularly applicable for use in the deliveryconduite tor illuminating gue and may be ioiliiiaed at any de- .siredpoint alongsaid delivery coinluit.

My invention coinsists in providing a liquid Collection pocket orchamber and so arranging the gas conduit that when a predeterminedquantity of liquid hooiV collected the l'low oi. gas will not becompletely stopped,

but will be restricted to such an extent that the size of the gas tlainewill unmodiately indicate the reduction of the tlow ot gas and permitthe liquid to be withdrawn before the supply of gas is entirely shut offby the accumulation of Jfurther liquid.

Reference is to be had to the aceompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views:

Figure l is a front view of a gas meter, having the inlet and outletpipes oonstrueted to embody7 my invention; Fig. 2 is a vertical sectionthrough a` portion ot' the gras servico pipe, constructed in accordancewith niy iuvention, and Fig. B is a transverse section ou the line 3-3of Fig. 2.

In gas meters it ifs customary to provide a gas inlet Conduit l0 and agaa outlet oonduit ll upon opposite sides; thereof and leading to themeter :from above. lhe que inlet conduit is substantially identical withthe gas outlet and each eonneets with the interior oi" the meter throughau aperture l2, adjacent'` the upper portion of said meter. Below theaperture eaeh conduit extends downward to 'torni a pooket, chamber orreceiver ll, iu which liquid may be collected below the aperture l2without l'lowingI through Said aperture into the meter to inof thelatter.

lterl'ere with the operation v olE liquid collect l Should a sul'lieientquantity in this pocket or receiver so that the level would rise loclef-Le the apta-ture l2, the liow oi"i gas lluctuates with suoliviolence as to Sometimes extinguish the lights. ln thisl specific lio'rmot' meter, l contemplate the' inlsertion ot' a partition l-l connectedto the side ot the gus conduit above the aperture l2 and extendingldownward to a point a considerable distance below said aperture. The gasin entering through the conduit l2 muet pass-1 beneath the lower edge ofthe partition and up on the` opposite eide thereof to reach the aperturel2. ln flowing troni the meter it must paus beneath the lower edge otthe other partition before escaping' through the outlet conduit. Thepartition serves to divid(I the lower portion ot' the conduit into two`separate passagers' l5 and lo, the Yformer leading down\.vard on oneside ot the )artition and the other leading upward on the other side otthe partition, and the two passages commuuicating` with each otherthrough the liquid collection pocket or chamber at the lower end.lreterably the upward passage is ot' slightly greater size. than thedownward passage, so as to prevent the liquid from being forced up theoutlet passage should it rise to the level of the lower edge of thepartition. In

l the partition l provide an aperture 1T adjacent the aperture but otconsiderably smaller size.

Duringthe normal operation of the del vice a small portion of the gaswill pass through the aperture 17, but the major p0rtion will passbeneath the edge of the partition. Any liquid within the gas; willcollect in the pocket lf3, and should this liquid collect to such anextent as to reach the level of the lower edge ot the partition, themajor portion of the tlow ot ,ons will be, cut oli'` but the aperture lTwill permit a small quantity o'l gas. to flow, and thus the lightswliioh may be burning;l will not be coinpletely extinguished. As soon asit is; noticed thaty the, llame at the several burners is greatlyredueed iu size, it will be` known Lthat the liquid Should be pumped outor otherwise removed. lt' desired, a second aperture 'lli' may beprovided in the part-ition. somewhat; larger than the aperture li", sothat a sel-oud warning will be` `iveu when the liquid rises to closethis aperture.

In utilizing my invention in connection with gas service pipes andindependently oi.' the meter, the partition is preferably annular inform and constitutes an inner pipe concentric with the walls of theliquid collecting pocket or chamber. ln Figs. 2 and .15 I have lshown anattachment adapted tor use in gas service pipes7 in which the gas.supply conduit l()a and the gas delivery conduit lla both comnuinieatewith the liquid collecting chamber 13% The pipe l0 is preferably securedto the side of a iitting 1.9, and at the lower end of the fittingextends the pipe E20, closed at its lower end by any suitable form ofcap 21. The cap may, if desired, carry a plug 22, which may be removedto permit the draining` of the liquid chamber. The fitting at its upperend connects with the pipe 1l", and a pipe 14a, constituting apartition, is secured in alinement with the pipe 11a which extends intothe pipe 20. The pipe 14a is enough .smaller than the pipe 20 so thatits interior cross sectional area is slightly greater than the crosssectional area of the annular passage between the pipes. The pipe lieta,forming the partition is provided with an aperture 17, adjacent theconnections between the Fitting and the pipe 10a. The gas enteringthrough the pipe 10 passes downward to the liquid collection chamber13Ll and up the pipe 14a. lVhen the liquid rises to such al height inthe lower end of the pipe 10a that the gas cannot pass beneath thepartition, it may still pass through the aperture 17a but at a reducedrate, so that the ditierence in the volume of the flow of gas asindicated by the diminished size of the gas flame will show that it isnecessary to withdraw the water from the chamber 13L to allow the gas toresume its normal How.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

In a conduit for delivering heating or illuminating gas, means forseparating liquid 'from said gas and indicating the presA ence of apredetermined quantity of said liquid, con'iprising, in combination, adownwardly-extending passage adapted to be connected to a source ofsupply, an upwardly-eatendingl gas passage adapted to deliver to aburner, a liquid-collecting chamber connecting said passages at theirlower ends, and a small aperture or passage connecting said passagesabove their lower ends, the downwardlyextending passage, the liquidchamber, and the upwardly-extending passage constituting the maindelivery passage for the gas and having a capacity to atord a supplysufficient to support a full or normal flame at the burner and the smallaperture or passage constituting an auxiliary or safety passage andhaving a capacity to aiiord a supply sufficient only to support a flamereduced markedly below the normal when the collection of liquid withinthe liquid chamber closes communication between the upwardly anddownwardly-extendingl passages.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
